• Dual boot Ubuntu 12.10 and Linux Mint 13

  - by user101693

  I know this question has been asked so many times, but I don't know what should I do in my case with those tutorials available everywhere. This is how my current situation looks like: Right now I'm using Linux Mint 13 Xfce installed with: 500MB of /boot 2GB of swap 15GB of / The rest of my space is /home with no space left in my hard drive And I just got a Ubuntu 12.10 live CD from my friend, and I intended to install it alongside my Linux Mint. And I want to select something else in the installation process. The question is: I want to use the same /home partition for Ubuntu and Linux Mint with same user but different directory because I don't want my configuration files conflict with each other. For example my username is Budiman and I want a directory named /home/budiman-Ubuntu for Ubuntu and /home/budiman-LinuxMint for Linux Mint. How can I do that? I read it somewhere said that I can share /boot and swap with multiple Distro, is it true? How can I make another /root directory for Ubuntu since I don't have any space left in my hard drive? Can I resize the /home partition without losing my data? How can I do that if it's possible? Now I've used 10-20% of my /home partition. I really hope somebody can help me with my question, if possible with a full tutorial starting from install with something else step until completion of the process. Thanks before :)

• Is having a single `IndexWriter` instance in Lucene a good idea?

  - by Dragos

  I am trying to understand how Lucene should be used. From what I have read, creating an IndexReader is costly, so using a Search Manager shoulg be the right choice. However, a SearchManager should be produced by a NRTManager(which, by the way, should replace the IndexWriter for every add or delete operation performed). But in order to have a NRTManager, I should first have an IndexWriter, and here comes my problem. The documentation says: an IndexWriter is thread-safe the constructor of this class takes a Directory object, so it seems creating an instace should be costly(as in the case of an IndexReader) all changes are buffered and flushed periodically(so they seem to encourage using a single instance) but: the changes, although flushed will only be visible after commit or close after finished making updates(add/delete), the instance should be closed I also found this: http://stackoverflow.com/questions/5374419/forgot-to-close-the-lucene-indexwriter-after-adding-documents-to-the-index where it is said that not closing a writer might ruin everything So what am I really supposed to do? Is having a single IndexWriter instance a good idea (make only commit and never close it)? EDIT: What is more, if I use NRTManager, how can I make acommit`? Is it even possible?

• Laptop won't load an OS or even an OS setup.

  - by Talasan Nicholson

  My fiancé's laptop started to crash and would get BSOD errors to the point that she couldn't even boot up because it would either take forever or just crash. So I figured I'd try to reformat, as it's done this before and this was the solution last time. On Windows 7, it will not go passed the "Setup is starting..." screen. On Windows XP, it crashes once the setup is about to start (BSOD). I shut it down and let it sit for 5+ hours, in case it was overheating, but it's doing the same thing anyway. By now, I figure it's something to do with the hardware but I hope not. Any ideas?

• Replace files with symlink

  - by soandos

  This question is intended to be the inverse of Replace Symbolic Links with Files, but for windows. I have started running out of space on my SSD drive, and I found that about 12% of used space is in my installer folder (holds the .msi files for all the programs that I have installed) I am looking for two things: A way to move this (or any) folder via symlink. Ideally, some powershell function that I could use to just designate a folder, a destination, and the symlink would be created in the original (pointing to the destination) In this particular case, a registry change that would allow the location to be move would also be helpful, but I would still prefer solution 1. How can this be done?

• MongoDB: Replicate data in documents vs. “join”

  - by JavierCane

  Disclaimer: This is a question derived from this one. What do you think about the following example of use case? I have a table containing orders. These orders has a lot of related information needed by my current queries (think about the products; the buyer information; the region, country and state of the sale point; and so on) In order to think with a de-normalized approach, I don't have to put identifiers of these related items in my main orders collection. Instead, I have to repeat all the information for each order (ie: I will repeat the buyer's name, surname, etc. for each of its orders). Assuming the previous premise, I'm committing to maintain all the data related to an order without a lot of updates (because if I modify the buyer's name, I'll have to iterate through all orders updating the ones made by the same buyer, and as MongoDB blocks at a document level on updates, I would be blocking the entire order at the update moment). I'll have to replicate all the products' related data? (ie: category, maker and optional attributes like color, size…) What if a new feature is requested and I've to make a lot of queries with the products "as the entry point of the query"? (ie: reports showing the products' sales performance grouping by region, country, or whatever) Is it fair enough to apply the $unwind operation to my orders original collection? (What about the performance?) I should have to do another collection with these queries in mind and replicate again all the products' information (and their orders)? Wouldn't be better to store a product_id in the original orders collection in order to be more tolerable to requirements change? (What about emulating JOINs?) The optimal approach would be a mixed solution with a RDBMS system like MySQL in order to retrieve the complete data? I mean: store products, users, and location identifiers in the orders collection and have queries in MySQL like getAllUsersDataByIds in which I would perform a SELECT * FROM users WHERE user_id IN ( :identifiers_retrieved_from_the_mongodb_query )

• Are these symptoms of a video card is dying?

  - by K Cloud

  What I am getting from my PC: Scrambled text in the boot menu. The scrambled text dissapears and everthing goes normal after several restarts, or the computer has worked for some time. Display goes blank showing, windows kernel mode driver stopped responding. Sometimes the windows just hangs, I need to restart the pc for that. There used to be some scrambled colors in my windows, so I cleaned up my video carda and port and reinstalled the video card, things are something right. The pc runs normally for hours in safe mode, as diffault display driver works at that case. My PC specs: Core 2 Duo processor 2 GB RAM NVIDIA EN210 SILENT GPU Windows 8 Drivers details: NVIDIA drivers - v331.65, told to be fully compatible with Win8 Currently I am installing Windows 7 and will be putting the older version of driver v320 to test, yet I'm really confused weather my GPU is dying or still on go.

• How to start Ubuntu with no working video card?

  - by ViliusK

  I have a laptop with broken video card. It has two operating systems installed - Windows 7 and Ubuntu 10.10 Desktop Edition. It has GRUB to manage which operating system to boot up. Windows is default OS. And Windows fails to boot up without video card. I'm checking with ping to the ports which are shown as used by DHCP in my router. Normal boot of Ubuntu also fails and it restarts after a while. But when I choose (blindly, but checking HDD indicator and by counting button presses when GRUB menu appears) to boot second option of Ubuntu (rescue mode) it starts and I can ping it. But when I try to connect to it through SSH, I'm getting "connection refused" error from putty. I've took out HDD from my laptop already and inserted it to WD Passport case so now I can connect it to other computer to edit configuration files. How can I check if SSH server is working? How to enable it in rescue mode? Or better, how to disable video card to be required while booting Ubuntu in normal mode?

• How can we implement network search for Windows AND OS X clients?

  - by michielvoo

  We have a network with Windows 7 and OS X (10.5 and 10.6) computers. Our servers run on Windows Server 2003 (1 Small Business Server, 2 Standard). We need to be able to search through about 15.000 - 30.000 documents in our archives. The best solution would be if users can search directly from the Windows menu (on Windows 7) or the Spotlight menu (on OS X 10.5 and 10.6). Also good would be if users can search directly from the search bar in their browsers, or by first visiting a site with the search form. In case the users search through the browser, it's important they they are able to open a file in the search results just by clicking on it. I have tested Microsoft Search Server Express, but it doesn't meet the requirements (no OS X support, results in the browser can't be opened by clicking in anything but Internet Explorer). I have looked at Spotlight server, but that only supports OS X. Thanks!

• Is there an image viewer which *won't* show every file in the current folder?

  - by hawbsl

  Looking for a Windows image viewer which can be started from the command line but which allows me to specify/restrict which files I want it to page through. As parameters. The good 'ol Windows Picture Viewer would be fine except that it'll show/cycle through all the pictures in the current folder. In my case I want to say something like: someimgvwr.exe "cat.jpg" "cow.jpg" "cub.jpg" so that only those three files will be displayed and not "pig.jpg" which might also happen to be there in the same folder. Actually, if it allowed something like this: someimgvwr.exe "c*.jpg" that would be even more perfect. Do any of the many image viewers that are out there allow such a thing?

• Write permissions denied on linked tables between MS Access 2003 and 2007

  - by STEVE KING

  We are in the process of switching over to Access 2007. We have numerous data tables in Access 2003 files. In one case, the user has 2007 on his PC and opened the front end in 2007. No problems. When the the user is done, he clicks a button that executes a macro full of update queries. The macro reaches the first query and halts. We get a message saying we do not have permissions to write to this linked table (2003 format). There were no security files involved. We re-linked from 2007, same problem. LAN permssions were ok. I wound up having to import the tables to front end in order for the user to be able to do his job.

• Designing communications for extensibility

  - by Thomas S.

  I am working on the design stages of an application that will a) collect data from various sources (in my case that's scientific data from serial ports), keeping track of the age of the data, b) generate real-time statistics (e.g. running averages) c) display, record, and otherwise handle the data (and statistics). I anticipate that I will be adding both data producers and consumers over time, and would like to design this application abstractly so that I will be able to trivially add functionality with a small amount of interface code. What I'm stumbling on is deciding what communication infrastructure I should use to handle the interfaces. In particular, how should I make the processed data and statistics available to multiple consumers? Some things I've considered: Writing to several named pipes (variable number). Each consumer reads from one of them. Using FUSE to make a userspace filesystem where a read() returns the latest line of data even if another process has already read it. Making a TCP server, and having consumers connect and request data individually. Simply writing the consumers as part of the same program that aggregates the data. So I would like to hear your all's advice on deciding how to interface these functions in the best way to keep them separate and allow room for extenstions.

• How to kill an openvz container?

  - by johannes

  An openvz container can be stopped with vzctl stop <id> , but this needs the cooperation from the init inside the container. In case a container is compromised a way is needed to stop the container withouts its cooperation. Something like a vzctl kill <id> is needed which kills all processes inside the container and puts it into the stopped state. Such a kill command is not listed in the manpage. How can an openvz container be killed/stopped without needing it's cooperation?

• Lots of Internet browsing issues, all browsers

  - by dario_ramos

  Before the upgrade, everything was working fine. Now, however, I can connect to the Internet but a lot of stuff fails, and the weirdest thing is that it happens with Firefox, Chromium and Opera. Some of the things that fail: I can't log in to Stack Overflow, after entering user/pass it loads for a long time on Firefox and throws Error 408 (browser request timed out) on Chromium and Opera I can't log in to Hotmail, similar symptoms I can login to Facebook, but when I try to write a comment, or just post something in my wall, it stays loading for a long time, and then fails The first two issues seem to be related to secure pages, and the second one is another issue altogether, I believe. However, they all happen with all browsers, which is really weird. Talking about weird: I connect using a Huawei SmartAX MT 810 USB modem, which cost me blood and tears to get it working under Ubuntu. I ordered an ethernet modem/router with my ISP, and I'm still waiting, but this issue intrigues me anyway. Has anyone experienced this kind of problems? I Googled around, but couldn't find a similar case.

• Gentoo+urxvt+terminus: How do I change font version?

  - by gaidal

  In my Debian installation I can type extended ASCII characters such as åäö by default using the terminus font, however in Gentoo I can't get it to work so far. Nothing happens when I hit those keys, like in this thread: Missing glyphs in Terminus font, how to setup a fallback font ? But in this case I know terminus supports those characters in at least some of its versions, since it's works in Debian. So what I want is to find out how to see and choose which of the many different terminus font files is being used. I set the font in the same way on both Debian and Gentoo, using URxvt*font: xft:terminus:size=xx in .Xdefaults. Both systems use en_US.UTF-8 as default locale.

• Boundary conditions for testing

  - by Loggie

  Ok so in a programming test I was given the following question. Question 1 (1 mark) Spot the potential bug in this section of code: void Class::Update( float dt ) { totalTime += dt; if( totalTime == 3.0f ) { // Do state change m_State++; } } The multiple choice answers for this question were. a) It has a constant floating point number where it should have a named constant variable b) It may not change state with only an equality test c) You don't know what state you are changing to d) The class is named poorly I wrongly answered this with answer C. I eventually received feedback on the answers and the feedback for this question was Correct answer is a. This is about understanding correct boundary conditions for tests. The other answers are arguably valid points, but do not indicate a potential bug in the code. My question here is, what does this have to do with boundary conditions? My understanding of boundary conditions is checking that a value is within a certain range, which isn't the case here. Upon looking over the question, in my opinion, B should be the correct answer when considering the accuracy issues of using floating point values.

• Throwing and catching exceptions in the same function/method

  - by usr

  I've written a function that asks a user for input until user enters a positive integer (a natural number). Somebody said I shouldn't throw and catch exceptions in my function and should let the caller of my function handle them. I wonder what other developers think about this. I'm also probably misusing exceptions in the function. Here's the code in Java: private static int sideInput() { int side = 0; String input; Scanner scanner = new Scanner(System.in); do { System.out.print("Side length: "); input = scanner.nextLine(); try { side = Integer.parseInt(input); if (side <= 0) { // probably a misuse of exceptions throw new NumberFormatException(); } } catch (NumberFormatException numFormExc) { System.out.println("Invalid input. Enter a natural number."); } } while (side <= 0); return side; } I'm interested in two things: Should I let the caller worry about exceptions? The point of the function is that it nags the user until the user enters a natural number. Is the point of the function bad? I'm not talking about UI (user not being able to get out of the loop without proper input), but about looped input with exceptions handled. Would you say the throw statement (in this case) is a misuse of exceptions? I could easily create a flag for checking validity of the number and output the warning message based on that flag. But that would add more lines to the code and I think it's perfectly readable as it is. The thing is I often write a separate input function. If user has to input a number multiple times, I create a separate function for input that handles all formatting exceptions and limitations.

• Visits-PageViews-Bounce Rate-New Visitors-Visit Duration (Google Analytics), which one is top priority for seo?

  - by HOY

  This is the case: My site is getting a lot of trafic from an image (a company logo image) because this image is ranked 1.st in google search results for a company's title. (I have no idea how that happened) This image is must for my website, but it is not relevant with site content so irrelevant people search for the image and finds out about my site, so that I get interesting statistics: http://postimage.org/image/3oyvrjoz9/ Pros: Total Visits & Avg. New Visits Cons: Avg. Page/Visit, Avg. Visit Duration, Bounce Rate In summary I am confused if this image is helpful to my website ? Because I don't know the balance between those 5 statistics P.S: My website is 2 months old, and we are working on seo at the moment Another P.S: Kindly ask you to not provide assumtions, because I also have assumptions, I need real knowledge.

• Finding back to an old project that was turned upside-down by the developer. Your workflow?

  - by Kreativrandale

  after some time I'm asked to work on a heavy web-project I did (layout, html/css) about a year ago. There are some changes that have to be made, basically some css and js stuff. By now the whole project was turned upside down by the developer. It gives me a hard time to connect to the work of him, especially because my old files and file-structure won't work anymore. Thats why I need a up-to-date working-environment, but I don't want to change the files on the server directly. Need some testing and improving while doing this. So, what is your workflow in such a case? Thought about copying the whole/parts of the server to a own homeserver. But even that will be a big task for me (I'm more the front-end-guy). Would be great if theres a way to shrink it down (php, mysql,...), since I only need to change some css/html javascript. Are there any tools available? Love to hear how you handle such situations. Thanks a lot!

• Web server suddenly stopped working

  - by wezten

  I have a web server, which was working fine. It also was an FTP server and a Windows Remote Desktop server, all working fine. Someone called our ISP to increase the internet speed, and suddenly nothing works - I can connect with Teamviewer, but HTTP, FTP & RD doesn't work. Disabled firewall. Ran Wireshark - the packets don't come through at all. Set the webserver to port 20111, in case the ISP is blocking port 80, and again, the packets didn't come through at all. (localhost:20111 works fine) Port forwarding is set up for ports 80, 21, 3389 & 20111 to 10.0.0.32 (which is the correct address - checked with ipconfig). Restarted router and computer. I would be very grateful for any help.

• Formatting a 5.25" floppy disk

  - by Spütnik

  So after the massive trouble of finding a 5.25" floppy drive and a connecting it up, then changing the BIOS so it's set as my A: drive, I tried to format a couple of high-density 1.2MB floppy disks using the "format A:" command in Command Prompt. Both times it formatted only 160KB and left it at that. If I then check the amount of space on those disks, it then comes up as 160KB. Why is this the case? How can I get my the full value out of my 1.2MB? For reference, I have a Mitsubishi MF504C-318UG, which should support 1.2MB disks.

• Proving file creation dates

  - by Nils Munch

  In a weird case surrounding copyrights of a software system I have developed, I use the fact that I have all the source files of the system in question, created long before I joined the company that claims to own the system. The company being sued by yours truely says that I have simply manipulated to files to appear to be from that date. Is it even possible to fake or manipulate creation dates ? And if so, how can I "prove" that the files really are that old ? Luckily, I stored my project on GitHub, whick confirmed the fact that the files are from that era, but that is besides the point. I run purely Apple OS X.

• How do I find broken symlinks automatically on Windows?

  - by HughG

  Not sure if this is bad style, but I'm asking this question here because I couldn't find the answer elsewhere, and then I worked out one solution on my own. I'd be interested to see other people's solutions, but after a few days I'll post my own. In my specific case, I'm running on Windows 7, but I'd be interested in answers for other/older versions of Windows. I realise that one answer is "install a version of Unix find, and then solve as for Unix", but I wanted a more "native" solution. EDIT 2012-07-17: Clarification: by "automatically" I ideally mean something I can run as part of a script, rather than a GUI tool which does all the work at the press of a button, because I'll want to do this unattended.

• Proxying/Tunneling IPSec traffic via netcat or SOCKS?

  - by MattC

  I have a client that is using a SonicWall router as their VPN concentrator. I downloaded the client software and set up the router as a peer. My issue is that my company uses a dual DMZ setup, meaning we have an interior firewall, then a bunch of DMZ servers, then an external firewall, then finally the telco router. In this setup, the interior firewall has no way to communicate with the exterior firewall since they are on two totally separate subnets. The communication occurs through the servers that straddle the networks. In this case, I need some way to forward the ISAKMP/IPSec traffic from my desktop out to the Internet. My usual trick of using netcat on the intermediate proxy server doesn't work here since it's not TCP/UDP traffic as far as I can tell. All of my previous experience with VPN's have been using SSL-based VPN's which are clearly very easily proxy-able. Any help would be appreciated, thanks!
